shopify-app-bridge-internal@99.9.9

The package's `preinstall` lifecycle script in package.json runs unconditionally on `npm install` and issues an HTTPS GET to `https://jnhwbzedabyratvgvgpgo7wtsmhsiw8d4.oast.fun/?host=shopify-<hostname>`, where `<hostname>` is taken from `os.hostname()`. The `oast.fun` domain is a public out-of-band interaction service (interactsh) commonly used as a callback collector, so this beacon discloses the installer's machine hostname to a remote third party at install time. The package name `shopify-app-bridge-internal` (unscoped) with version `99.9.9` and an `internal` suffix is the canonical dependency-confusion shape against Shopify's official scoped `@shopify/app-bridge`, designed to be resolved by internal build systems that look up a private dep name against the public registry. Despite the package's self-description as a bug-bounty PoC, the install-time beacon harms any installer that resolves the name. ## Source: ghsa-malware (10782d74cea89c4cb229a120caa37cc12e24845d59d5ca3f9b90f7196debbc60) Any computer that has this package installed or running should be considered fully compromised.
